CellAlarm GSM

The CellAlarm-GSM is an alarm communication device that allows any make and model of alarm panel to transmit alarm signals to any Alarm Monitoring Center over the 2G Cellular GSM Network using a GSM voice channel. It is generally used as a backup device, however, it can just as easily be used as the primary device for cell-only monitoring applications. It interfaces via an RJ11 phone cable with an alarm panel modem or digital communicator to make a wireless phone call to a conventional alarm receiver at your Monitoring Center.

GSM Alarm Communicator

A standard analog alarm receiver like an Ademco or Surgard, cannot tell the difference between an alarm signal sent over a PSTN landline or one sent from a CellAlarm GSM. The role of the CellAlarm GSM is to connect any alarm panel or medical PERS unit to any alarm receiver over a GSM mobile phone network. Once the connection is made, communication between the alarm panel and alarm receiver is identical to what it would have been if the call had been made using a PSTN landline.

This means that the device is "Protocol Independent". In other words, it does not matter whether your alarm panel is programmed to use a DTMF, pulse or FSK alarm protocol. As long as the alarm receiver supports the chosen protocol - the CellAlarm GSM will allow your panel to communicate. There is no requirement to reprogram the alarm panel if the system was previously monitored over a phone line. There are no programming options on the CellAlarm-GSM, so you simply unplug your panel from the phone line and plug it into the CellAlarm-GSM.


Important Notice: GSM Voice technology will be available via T-Mobile in North America after 2017

The CellAlarm-GSM device operates using 2G technology on GSM networks which may no longer be available with AT&T after January 2017. If you are in the USA or Canada, then IP Alarms feel that is something you should be aware of so that you are able to make an educated decision on whether or not you would like to invest in this technology. The longevity of the 2G network varies from provider to provider in each country, so please do your research.
